Biometric Cryptography

Biometric cryptography combines unique physical or behavioral traits—like fingerprints, iris patterns, or voice—with cryptographic techniques to securely generate and protect cryptographic keys. This approach ensures that a person's identity verifies access automatically, without needing traditional passwords. It enhances security by tying the key directly to a distinctive biometric feature, making unauthorized access difficult if the biometric data is kept secret and protected. This method is useful in secure systems where reliable, user-friendly authentication is essential, providing both convenience and strengthened security by relying on inherently unique human traits.
